Bluetooth intermittent

It used to connect. Now it doesn’t. Connectivity has always been intermittent at best. Don’t get me wrong, it’s easy enough to open the bonnet and press the button to change settings but that’s not the point. It’s an expensive item that in truth will never pay for itself but one would expect it to be fully functional.

Issues resolved

After some issues with connectivity the team at tdi tuning replaced my tuning box and all appears to be working as it should now.
